Well not really of course. I am still using PM but have been trying out other clients recently : Emclient, Pegasus and of course Thunderbird. But none of them really do as well all round as PM.
The biggest problem I see is that some emails are just blank these days and have to be either sanitized or viewed in browser.
Then I had a eureka moment, scripts ! I assigned the 'view in browser' script to button 1 so that to view a non displaying email all I do now is click the number 1 button instead of remembering where in the menu bar the option is.
I might be writing this to myself of course but if there is anybody out there then please let me know.
TIA
